The impregnated diamond core bit is the most commonly used bits in mineral exploration and the geotechnical drilling industries, China Geo-Equip Tech (CGET) can offer the drill bits for underground and surface exploration applications. The matrix layer of our bits crown contains a uniform distribution of synthetic diamond crystals by carefully selections that are embedded in the special made matrix by decades years of experience. When the matrix layer is eroded, the new layers of sharp synthetic diamond will be exposed until the matrix layer of the bit crown is consumed totally . The function of the impregnated diamond core bits, such as overall bit life and penetration rate are dependent on the grain size, concentration and grade of the synthetic diamond crystals as well as the relative hardness and property of the metal bond materials.
-
CGET has developed a range of impregnated diamond matrices with matrix layer metal bonds that range from hard, abrasion resistant types to soft, ductile types.This includes full range high tech and high quality drill bits with different crown profiles. There are two series for IMP bits are very popular by our customers, one is known as MASTER another is NAVIGATOR, all of them have wonderful engineering and special designs, experts in powder metallurgy with sophisticated sintering and CNC machining, strict quality control and precise gauge protecting technology, all of those procedures are only for ensuring best work-life & good penetration rates, especially for MASTER bits, which are widely used in Mideast countries, Russia language speaking countries, Australia and South America for tackling tough rock conditions. Not only for IMP bits, but also we provide Surface-set Diamond bits, PDC bits and be able to have the ability to design the bits according to our customers specified requirements.

Different profiles of the bits shapes are for our customers to achieve best of performance according to various of rock formations

STD Profile
General purpose design, suitable for a wide range of rock formations
Great performance of fluid circulation for cooling the bits
Customized design for the numbers of waterways easily
Available with wider or larger waterway channels -
W/N Profile
Configuration of the water channel is wider than STD profile, special wedged shape can reduce the numbers of channels
W/N bit allows high flushing volume
Higher rotation speed is recommended
Recommended for soft and broken ground applications where blocking of regular waterways is possible.
Available with wider or larger waterway channels -
Turbo profile
Partial waterways are added between each channel configuration
Bit-rock contact area is reduced 20% compare to STD profile bit, it has greater penetrations rates in competent formations ( Hard to very hard or slightly broken formations)
Free cutting of waterways with greater ejection of fluid and reducing pressure across the bit face because of jetting effect. Higher rotation speed is recommended
Available with wider or larger waterway channels -
FD profile
Recommended for very soft and broken formation works with triple tubes coring
FD ports offers excellent flushing to prevent blockage in waterway channels and minimize flushing of core sample and reduce the undesirable core erosion
Available with wider or larger waterway channels
